LatLon distance软件

Find distance between two points based on latlon coordinates

软件应用简介

This functions finds distance (in km) between two points on Earth using latitude-longitude coordinates of the two points. Distance is calculated using two distance funstions: Haversine and Pythagoran. The first output is based on Haversine function, which is more accurate especially for longer distances.

–Inputs: 

latlon1: latlon of origin point [lat lon] 

latlon2: latlon of destination point [lat lon]

–Outputs: 

d1km: distance calculated by Haversine formula 

d2km: distance calculated based on Pythagoran theorem

–Example 1, short distance: 

latlon1=[-43 172]; 

latlon2=[-44 171]; 

[d1km d2km]=distance(latlon1,latlon2) 

d1km = 

137.365669065197 (km) 

d2km = 

137.368179013869 (km) 

%d1km approximately equal to d2km

–Example 2, longer distance: 

latlon1=[-43 172]; 

latlon2=[20 -108]; 

[d1km d2km]=distance(latlon1,latlon2) 

d1km = 

10734.8931427602 (km) 

d2km = 

31303.4535270825 (km) 

d1km is significantly different from d2km (d2km is not able to work for longer distances).
